Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the primary process that turns sediments into sedimentary rocks?
A
organisms walking on layers of sediment, pressing particles together tightly
B
minerals within sediment, absorbing water, and undergoing a chemical reaction
C
upper layer of sediment, pressing down on lower layers of deposited sediment
D
magma cooling under the surface of Earth, crystallizing to form rock
Explanation: 

Detailed explanation-1: -Finally, lithification is the process by which clay, sand, and other sediments on the bottom of the ocean or other bodies of water are slowly compacted into rocks from the weight of overlying sediments. Sedimentary rocks can be organized into two categories.

Detailed explanation-2: -Sediment becomes a sedimentary rock through a process known as lithification. Lithification begins when rocks are buried and become compacted. The pores of the rock then become filled with cement, and certain minerals begin to recrystallize.

Detailed explanation-3: -LITHIFICATION-the processes of converting sediment into sedimentary rock through COMPACTION and CEMENTATION. Most important cements in sedimentary rocks: CALCITE, SILICA, IRON-OXIDES.

Detailed explanation-4: -Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice. Sediment can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by organic activity (e.g. as sea shells) or by evaporation.
